Be 1t lznown that we, CARL A. VONDER- IIEID und. HERBERT L.

in the art 110 which it appcrtains to make ancl use the Same. The object 01" the invcntion is t.o Provicle a simple ancl cfilcient apparatus by means of which heiler fiues, such as thosk usecl in fire tube boilers cau be scalecl anal clezinecl with facility ancl efficiency with the least possible ell'ort upon the part 01? the Opera tor or attenclant ancl with an expeclition which is impossible by pursuing the methods which are now in c ornrnon use ancl Which are clependent upon a 1nanual scrap ing 0f the scale which orclinarily nheres rather tcnaciously t0 the surlaces 01T the lzubes 01 flues; ancl with this object in vlew thc invention consists in a construction, combination ancl rclation ofparls 0f which 2L prellerrccl en'1bocliment is shown in the accompanying clrawings, wherein:

The apparatus consists es'sentlally cf axially parallel clcnner ancl bearing 10lls 10 an'd 11 0f which the forrncr is carriecl by a shaft 12 while the latter, employ6d in clu plicate t0 form a scat f0r a tube 01 flue 1 1-, are carriecl by a bearing=franie 15 fulcrurnecl as at 16 150 a sitahle upr ight 17 0f the supportlng; fra1ne und yiclclingly Supported at the other cnvl by a spring 18 01 its cquiva lcnt, a: handle 19 bcing conuectecl with saicl .f1a1no f01' afforcling manual c0ntr0l of the bczuring flzune und hcnce enabling thc operat0r t0 n10x e the bcaring rolls towarcl ancl frorn the cleaner roll as the operation of cleaning the flues 01 'tubes may require.
